QT 8bit vs Compressor DVD preset for DVD Authoring
Ok, I know there are a ton of forums debating this back and forth, but thought I’d start just one more repeating the same question about:
Is it better to
a.) Export your video out of FCP using QT, saving it as an “8-but uncompressed 4:2:2, then letting it be dropped into DVDSP to do the encoding (or)
b.) Exporting out of FCP, using Compressor, dropping a DVD Best Quality preset onto it and hitting “Submit”.Is there a significant quality hit from either, or a noticeably better quality doing it the other way, or any other way not mentioned, such as Export as a “Self-Contained” then dropping it into DVDSP. This also means we have verified all the sized and framerates stay the same, as well as deinterlacing, anything other than that, it what I’m looking at.
Thanks,

there is zero debate about this on this forum, nobody recommends bringing in a QT movie to DVDSP.
Why 8-bit uncompressed? If you are working with ProRes you just throw away a ton of color information. If you are using ProRes, DVCProHD, DVCPro50 or other professional editing codecs, just export your timelines as self contained, current settings.
There could be a debate on the settings in Compressor, I never use presets and almost always use CBR encoding. But compressing is an art, you need to test, what looks good for well prepared source footage will not work for noisy DV footage that has no contrast.

Larry Jordan talk about not exporting using Compressor, but using QT, as a self-contained, and letting DVDSP do the encoding, but others say it’s no difference. I’m exporting EX-3 footage, and self-contained to DVDSP is better, than exporting through Compressor then?

From a time-line exporting to 8bit uncompressed, then into DVDSP, I noticed better motion in the encoding by DVDSP, but exporting selfcontained, then to DVDSP, i noticed a ton of interlacing??

What about batch exporting using FCP, QT to QT Custom, then using h.264 as the codec, then dropping those into DVDSP, would that cause 2 compressions to occur or would DVDSP not need to recompress the h24 .mov’s.?

Search this forum on h264.
It should never be in your DVD workflow, never

Who ever Larry Jordon is, he knows very little about DVD or DVDSP…LOL

I talked to my Emmy-award winning editor friend John Crossman with Crossman Post in Sandy, Utah, and he said to output everything, everytime, as an 8-bit uncompressed QuickTime, then dropping that into DVDSP, so DVDSP will see the files, and make the compressions where needed, whereas Compressor may compress more than what quality you’re looking for, so I’m making it a habit. I did some tests, and after seeing the exports from FCP to Self-Contained to DVDSP, FCP to Compressor to DVDSP, and FCP to QT-8bit to DVDSP, the best results were from FCP to QT-8bit to DVDSP in color, motion, movement, picture quality, clarity, and overall output.

Can people be stripped of their Emmys for giving out incredibly bad advice? Ha Ha
Michael gave you the correct advice a couple posts up but if you like the work dvdsp does then so be it.
